- The use of PowerSpec is supported in North America only. For engines equipped with a Diesel Particulate Filter (DPF), Ultra Low Sulfur Diesel Fuel is required. Failure to do so can permanently damage engine and aftertreatment systems within a short period of time. This damage could cause the engine to become inoperable and affect the warranty coverage on the engine.
- Licensing: PowerSpec does not require a license to connect to a vehicle, read data, or use the gearing calculator. A license is only required to write changes to the adjustable features.
